I can't tell you what "commercial" cleaning fluid is for Epson printers,
but I can tell you the solution I use and have recommended to literally
thousands of people who have successfully used it with all Epson OEM
inks, and most dye inks. And it literally does reside principally under
you kitchen sink.
Buy any brand of ammoniated window cleaner. In North America that means
either Windex original formula (not the new types or all surface types)
or any generic "blue transparent" version but makes sure it has ammonia
in it.
In the UK, you can buy Windolene which is transparent clear original
(with ammonia). If you cannot find ammoniated window cleaner, you may
also use household NON-SUDSY ammonia and mix it one part ammonia to 9
parts water.
Once you have either the window cleaner or the diluted household
ammonia, add about 8 parts of that liquid to 2 parts of isopropyl
rubbing alcohol, either 70 or 99%, but make sure it is transparent,
clear, isopropyl containing no additives such as skin conditioners or
lanolin or other oils, or oil of wintergreen, etc.
I have tested this mix on dye, ultrachrome and durabrite inks, both wet
and dry, and it successfully dissolves all of them. I doesn't appear to
harm the head.
Some inks, Lyson makes some, have the opposite pH of normal Epson OEM
inks and most others. If the printer is using Lyson inks, be careful,
as some my clot with the use of a high pH cleaner as the one mentioned.
